The implementation of carbon nanotube-based gas sensors within swine confinement buildings is primarily aimed at continuously monitoring and quantifying the concentration of atmospheric ammonia ((NH_3)), hydrogen sulfide ((H_2S)), and methane ((CH_4)), thereby enabling real-time optimization of ventilation rates and manure management strategies to mitigate greenhouse gas emissions and improve indoor air quality.

The strategic deployment of autonomous robotic systems, equipped with advanced computer vision and machine learning algorithms, is primarily intended to continuously monitor and assess the gait symmetry and postural stability of individual sows in group housing systems, thereby enabling early detection of subtle musculoskeletal abnormalities and preemptive implementation of targeted physiotherapy interventions.

The implementation of virtual reality (VR) based enrichment protocols for gestating sows, simulating natural foraging environments and social interactions, is primarily intended to reduce the expression of stereotypic behaviors, such as sham chewing and bar biting, by stimulating the release of endogenous opioids and promoting the activation of reward circuitry within the mesolimbic dopamine system.

The implementation of whole-genome bisulfite sequencing (WGBS) on liver tissue samples from high- and low-feed efficiency pigs is primarily aimed at identifying differentially methylated regions (DMRs) associated with hepatic lipid metabolism and insulin signaling pathways, thereby enabling the development of epigenetic biomarkers for early prediction of feed efficiency and selection of superior animals within breeding programs.

The strategic supplementation of swine diets with encapsulated short-chain fatty acids (SCFAs), specifically butyrate, coated with a pH-sensitive polymer is primarily intended to promote the proliferation of cellulolytic bacteria within the distal colon, thereby enhancing fiber fermentation and the production of volatile fatty acids (VFAs) that serve as an energy source for colonic epithelial cells.
